BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of trench drains. More particularly, the present invention relates to trench drain systems that can be installed on level floor surfaces.

2. Background

Floors of shower rooms, garages, driveways, etc. are today often equipped with trench drains for drainage of water therefrom. The floor must be installed with a slope toward the trench drain whereby water on the floor may flow toward and into the trench drain. The trench drain must similarly be sloped toward an opening so that water falling into the trench drain may travel to and flow out through the trench drain outlet. The installation of a trench drain system with a proper floor slope to the trench drain and a proper trench drain slope to its outlet can be difficult and burdensome, especially when the trench drain must be installed over an existing level floor surface. Accordingly a need exists for an improved trench drain system and method of installation on level floor surfaces which is relatively easy to install and reliable, particularly for shower rooms.

SUMMARY OF THE INVENTION

In one form thereof the present invention is directed to a method of installing a trench drain on a level floor surface comprising the steps of: placing an elongate channel member on the floor surface, the channel member having a bottom surface, side walls extending upwardly therefrom to side walls top edges, a channel inlet between the side walls top edges and a drain opening; inserting a preformed elongate sloping member having a thick end tapering to a thin end into the channel on the bottom surface with the thin end closest to the channel drain opening, the sloping member forming an inclined surface sloping toward the drain opening; and, filling an area adjacent the channel over the floor surface with a material to the height of a channel side wall top edge, whereby liquid on the material may flow into the channel member through the channel inlet and along the inclined surface and out through the channel drain opening.

Preferably, the method further comprises the step of covering the inclined surface with an impermeable covering layer and the covering layer is preformed and is inserted into the channel over and covering the inclined surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring initially to FIG. 1, a shower room generally depicted by the numeral 10 is shown wherein a trench drain system 12 has been installed on a level floor surface 14. The trench drain system 12 is installed along the perimeter of the raised shower inclined floor surface 16 adjacent the shower vertical walls 18S, 18LS, 18RS and 18B. Preferably, the inclined floor surface 16 is covered with floor tile 20 and/or other sufficiently slip resistant and visually appealing surface covering. The inclined floor surface 16 slopes toward the elongate grate 22 of the trench drain system 12 whereby water sprayed thereon from a shower spray head 24 flows to the grate 22 for drainage away therefrom. It is contemplated that the trench drain system 12 of the present invention can also be installed in floors of rooms and areas other than showers and also for drainage of liquids other than water so long as such liquids can flow along the inclined floor surface 16 to the grate 22 thereof.

The preferred method of installation and trench drain system 12 includes an elongate channel member 26 which is preferably constructed by securely adhering together one or more preformed channel sections 28 including but not limited to: elongate straight channel sections 28S; 90° corner channel sections 28C90; 45° corner channel sections 28C45 (not shown); 30° corner channel sections 28C30 (not shown); channel bottom drain sections 28DB; and, channel side wall drain sections 28DS. Each of the channel sections 28 are generally U-shaped having a bottom wall 30 defining a bottom surface 30S; side walls 32 extending vertically upwardly from the bottom wall 30; and, rim projections 34 extending horizontally from the top of the side walls 32 and defining side walls top edges 34E. An elongate channel inlet 36 is, hence, defined between the rim projections 34 or side wall top edges 34E into the channel member 26. The bottom wall 30 of each of the sections 28 is horizontally disposed and is thereby adapted to be placed on a generally flat level floor surface 14.

The channel bottom drain sections 28DB include a drain opening/outlet 38 extending through their bottom wall 30. Similarly, channel side wall drain sections 28DS include a drain opening/outlet 38 extending through their side wall 32. Drain openings 38 are adapted for connecting a pipe 40 thereto in a known and customary manner. It is noted that one or more of each of the drain sections 28DB and/or 28DS can be used in a trench drain 26 installation.

The terminal ends of each of the channel sections 28 are provided with one of a female attachment groove 42 and/or a male attachment extension 44. Grooves 42 are adapted to slidingly receive the extensions 44 for attachment of the channel sections 28 to one another. Additionally, coupling members 46 may be used for joining shorter lengths to one another, and end cap members 48 may be used at terminal ends of an elongate channel 26 as, for example, shown in FIG. 9. Preferably, each of the channel sections 28, coupling members 46, end cap members 48 and pipe 40 are made of PVC plastic and are hermetically secured and sealed to one another with a PVC adhesive. As should now be appreciated, the several channel sections 28 are selectively attachable and secured to one another for forming any desired elongate shape channel member 26.

Trench drain system 12 includes a preformed elongate sloping member 50 adapted to be received in the channel member 26, through the inlet opening 36, and located on the bottom wall surface 30S for thereby forming an inclined surface 50I sloping toward the drain opening 38. The elongate sloping member 50 includes a terminal thick end 50K tapering down to a terminal thin end 50N, a bearing surface 50B, a top inclined surface 50I and side walls 50S. When inserted into the channel member 26, the bearing surface 50B sits or bears on the channel bottom wall surface 30S and the side walls 50S are located adjacent the channel side walls 32. Preferably, the preformed elongate sloping member 50 is made of a material selected from one or more of foam, plastic, and fiberglass.

As best seen in FIG. 5, sloping member 50 can be provided in stock long lengths 50L and severed for making any desired shorter length sloping member 50. In FIG. 5, the stock long length 50L is shown being severed into shorter length sloping members 50-1, 50-2 and 50-3. As best shown in FIG. 2, each of the shorter length sloping members can be inserted into the elongate channel member 26, end to end with each thick end 50K adjacent a thin end 50N, for thereby providing a continuous inclined surface 50I along the entire length of the channel member 26 and through the corner channel sections 28C90, 28C45 and 28C30.

As shown in FIGS. 4 and 9, the thin terminal end 50N is placed closest to the channel drain opening 38. Similarly, as shown in FIG. 2, the thinnest terminal end 50N of the short length member 50-1 is placed closest to the channel drain opening 38. Accordingly, the elongate sloping member 50 forms a continuous inclined surface 50I sloping toward the drain opening 38 so that water or other liquids that flow into the channel member 26 may flow along the inclined surface 50I and out through the channel drain opening 38.

Preferably, the preformed elongate sloping member 50 is sealed and/or covered with a preformed impermeable elongate covering layer 52. Covering layer 52 is preferably a thin strip of PVC plastic or other water impermeable material which can be cut to a length and width corresponding to the sloping member inclined surface 50I. As shown in FIG. 2, a longer length covering layer 52 has been cut to shorter length covering layer sections 52-1, 52-2 and 52-3 corresponding to and adapted to be inserted into the channel 26 over and covering inclined surfaces 50I of the respective short length sloping members 50-1, 50-2 and 50-3. The covering layer 52 is secured in place between the channel side walls 32 and over the elongate sloping member 50 with an adhesive and/or other bonding agents. Alternatively, a bonding or other plastically formable material can be poured or painted onto the sloping member inclined surface 50I for thereby forming an impermeable covering layer thereover and between the channel walls 32.

An elongate grate supporting member 54 is provided and adapted to set on and be secured on the rim projections 34 at the side walls top edges 34E. Supporting member 54 includes an outer rail 56, an inner rail 58, and ribs 60 extending therebetween for thereby forming large inlet openings 62. An elongate grate receiving channel 68 is formed and provided over the ribs 60 and inlet openings 62 and between the outer and inner rails 56, 58. The elongate grate 22 is adapted to fit into the grate receiving channel 68. Supporting member 54 is preferably made of PVC plastic and/or other water resistant materials.

As best seen in FIG. 3, the trench drain system 12 can be located adjacent a vertical wall 18, with the outer rail 56 of the grate supporting member 54 being located adjacent the vertical wall 18. Advantageously, vertical wall tile 64 can bear upon and be supported by the outer rail 56 when the wall tiles 64 are being adhered to the vertical wall 18. As also best seen in FIG. 3, outer rail 56 is sufficiently wide and includes a finish surface 66 so that the outer rail 56 can be placed abutting the vertical wall 18 and accommodate the thickness of the wall tile 64. That is, after the wall tile 64 has been secured to the vertical wall 18, the tile thickness does not interfere with and the finish surface 66 remains visible. More importantly, the grate receiving channel 68 is thereby located a short distance from the wall tile 64 so that the tile does not interfere with and so that the grate 22 can readily and easily be place in and removed from the channel 68.

The inner rail advantageously forms a lip for abutment of the floor tile 20. That is, after the area over the floor 14 and adjacent the channel member 26 is filled with a fill material 70 to the height of the side walls top edge 34E, inner rail 58 provides an abutting edge for the floor tile 20. This also locates the finish floor surface 16 as high as the grate 22 so that water thereon may flow from the finish floor surface 16 over and onto the grate 22.

As best seen in FIGS. 2 and 4, the grate supporting members 54 are miter cut at their terminal ends as indicated by the numeral 70 for accommodating and fitting over the corner channel sections 28C90, 28C45 and 28C30. As mentioned herein above, elongate grate 22 fits snugly in the channel 68 of the elongate grate supporting member 54. Grate 22 is similarly preferably made of PVC plastic and/or other water resistant materials. Grate 22 includes an elongate flat body 71 having a finish surface 72 and a plurality of inlet openings 74. For accommodating and fitting over the corner sections 28C90, corner caps 73 are provided and secured at the terminal ends of the individual grate sections 22 by inserting into the channel 68 at the mitered corners 70 of the grate supporting member 54.

Accordingly, with the grate 22 located in the grate supporting member channel 68, water and/or other liquids can flow from a floor surface 16 and from the vertical wall tile 64 onto the grate 22 and through the grate inlet openings 74, through the large inlet openings 62 of the grate supporting member 54, through the elongate channel inlet 36 into the channel member 26, along the inclined surface 50I and then out through the channel drain opening/outlet 38.

As mentioned herein above, after the elongate channel member 26 is placed on the floor surface 14, the area adjacent the channel member 26 over the level floor surface 14 is filled with a fill material 70 to the height of the side walls top edge 34E so that water and/or other liquids on the surface 76 of the fill material and/or the finish floor surface 16 may flow into the channel member 26. The fill material surface 76 is inclined having a slope toward the side walls top edge 34E and so, after installation of the floor tile 20 thereon, the tile floor surface 16 is similarly inclined having a slope toward the side walls top edge 34E.

Fill material 70 can be preformed and/or a plastically formable hard setting material. When using a plastically formable fill material such as concrete, preferably, a floor height setting post 78 is used for setting a desired height, higher than the side walls top edge 34E, and positioning the fill material and forming the inclined floor surface 76. Floor height setting post 78 includes a base 80 adapted to sit on the level floor surface 14 and a post 82 extending perpendicular and vertically upwardly from the base 80. Post 82 extends vertically upwardly to a terminal end 82 and includes stacked breakaway sections 86 separated by weakened areas 88. By severing at the weakened areas 88 and removing one or more breakaway sections 86, the height of the post terminal end 84 can be modified so as to extend to a desired height from the level floor 14 for thereby creating a reference plane (between the post terminal end 84 and the side wall top edge 34E) and for positioning the plastically formable fill material floor surface 76 at an incline sloping from the post terminal end 84 toward the channel side wall top edge 34E. After positioning, the plastically formable fill material is allowed to harden for thereby providing an inclined hard floor surface 76.

As shown in FIG. 6, a floor height setting post 78 can be used generally in the middle of a trench drain system 12 whereby the fill material floor surface 76 can be sloped, as indicated by arrows S, toward the elongate channel member side wall top edge 34E and/or grate 22 which extend around the entire perimeter. As shown and depicted in FIG. 7, several floor height setting posts 78 can be used when the perimeter/trench drain system 12 is not symmetrical whereby, again, the floor surface 76 can be sloped as indicated by arrows S toward the channel side wall top edges 34E.

As shown in FIGS. 10, 11 and 12, fill material 70 can be a preformed sloping sheet member 90 adapted to be placed on the level floor surface 14 and form the inclined floor surface 76. The sloping sheet member 90 includes a thick end 90K tapering down to a thin end 90N, a bearing bottom surface 90B, side walls 90S, and a sloping sheet member top inclined surface 90I. As shown in FIG. 11, sloping sheet member 90 can be cut from larger preformed sloping stock sheets 90L.

In use, sloping sheet member 90 is placed on the level floor surface 14 with its bottom surface 90B bearing upon the floor surface 14 and its thin end 90N adjacent the elongate channel member 26. The height of the channel member 26 indicated by arrows HC (from the channel bottom wall 30 or floor 14 to the side walls top edges 34E) and the thickness of the sloping sheet member 90 at its thin end 90N indicated by arrows HF are substantially equal, and so the sheet member inclined surface 90I forms the fill material inclined floor surface 76. As should now be appreciated, one or more preformed sloping sheet members 90 can be used as shown in FIGS. 10 and 12 for thereby filling the area adjacent the channel member 26 and over the level floor surface 14 and forming the inclined floor surface 76 sloping as indicated by arrows S toward the channel side wall top edges 34E.

Preferably, the preformed sloping sheet member 90 is made of a material selected from one or more of foam, plastic, and fiberglass such that the overall weight of the fill material 70 forming the inclined floor surface 76 is relatively small. This is particularly useful when the trench drain system 26 is installed on a structural floor 92 as, for example, depicted in FIG. 3. Structural floor 92 can, as shown, be constructed with a plurality of wood joists 94 and a subfloor layer 96 thereover, and for this and/or other reasons it may not be feasible to install a concrete raised floor thereon. In these installations, the preformed sloping sheet member 90 is particularly useful.

Referring now more particularly to FIGS. 14 and 15, a trench drain system 12 is illustrated wherein a channel side wall drain section 28DS is incorporated and a pipe 40 is connected to its opening/outlet 38. As shown, pipe 40 can traverse over the floor surface 14 to a desired location for connecting to an existing floor drain (not shown). A pipe 40 is shown in dash lines depicting an alternate floor drain whereto the drain opening 38 may be connected by traversing over the floor surface 14. Alternatively, as shown in FIG. 10, when pipe 40 is connected to a channel bottom drain section 28DB, pipe 40 traverses/extends through the floor surface 14.

While the invention has been described as having an exemplary design, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles.
